UNITED STATES FERDINAND FUNKE, OF EVANSVILLE, INDIAN MARINE STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 269,041, dated December 12, 1882,

Application tiled August 18, 1882. (No model.)

To all whom it may concern:

Be it known that I, FERDINAND FUNKE, of

Evansville, in the county -ot' Vanderburg, in

the State of Indiana, have invented certain neWand useful Improvements in Marine Steam- Boiicrs; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appert-ains to make and use the same, reference being had to the accompanying drawings,.which form a part of this specification, in which- Figure l is a front elevation of a set of mavrine steam-boilers of my improved construetion, and Fig.2isa longitudinal sectionthrough one of the boilers on line w .fr in Fig. 1.

Similar letters oi' reference indicate corresponding parts in both the figures. y

Wy invention has relation to steamboatboilers adapted to boats where more than one boiler is used for generating steam. w By the old method, as commonly practiced in river boats, the several boilers are connected not only by a common steam-drum and common steamppe, but also by what is known as the mud` drum,77 in which the sediment is collected. The mud-drum connecting the several boilers acts as a conduit from one boiler to another in the series, so that when the boat is rocked or tilted the lilies in the boiler on the highest level are apt to be laid bare. This is a tittiiig and dangerous source of explosions, inasmuch as the lue or iiues when not covered by water are apt to collapse by overheating. Hence the object of my improvement is to so construct and arrange the boilers that the water in one cannot escape into any other boiler in the set or series.

In the present illustration of my invention I have shown a set of four steamboat-boilers, designated respectively by the letters A, B, G, and D. E is asteam-drum, which connects with the several boilers by short tubes e, thus receiving the steam from all ot' them, which' is fed to the cylinder ofthe engines through the steam-pipes F. vUnderneath each boiler, and connected to each bottom by the short vertical pipes g g, is the mud-drum or sediment-collector G, which is provided with a. blow-oil' valve, h. Thus it will be seen that each boiler has its separate mnd-drum, the several drums -being arranged parallel to one another between the walls H and l, upon which the set or series ot' boilers is supported. Each boiler is provided With a separate shutter or damper, K, for the purpose of shutting oil' d raft from the fines when desired.

If through any cause it is desired to throw any one ot' the boilers out of action, this may readily be effected by closing the valvef in its steampipe e, placing the shutter or damper K in position, as shown in Fig. 2, and opening the blow-oftl valve h, when repairs or other work may be done to the boiler without interfering with the other boilers.

I am aware of the PatentNo. 228,783, of 1880, and the construction therein set forth is not sought to be covered in this application.

Having thus described my invention, l claim and desire to secure by Letters Patent of the United States- In marine steam-boilers, the combination of a series ot boilers, each provided with its separate mud-drum G, having blow-olf valve h, and connected with a common steam-drum, E,

by pipes e, provided with cut-oli' valvesf, with the shutters K, adapted to shut off the draft from each boiler separately,substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto atlixed my signature in presence of two witnesses.

FERDINAND FUNKE.
